Summary

Keratoconus is a degenerative disease entity characterized by conical shape ectasia of the cornea. progressive conical deformation of the cornea leads to substantial astigmatism. Patients who are at an advanced stage of ectasia are often led to corneal transplant or other treatments, which essentially aim at correcting the refractive error and not in treating the ectasia. The top of the protruding cone that corneal configuration may be close to the visual axis or below and nasal of that. The disease manifests during adolescence, followed by slow progressive course, although it is possible to stabilize anytime. In 85% of cases both eyes are affected, but the severity of the attack can present significant asymmetry.
